IMO you can't go wrong with getting a finesse setup. You should still have plenty left to buy whatever else you need.
My suggestion is a 6.5 - 7' Medium with a MF tip. A 3000 series reel. 8lb Seaguar Invizx Fluorocarbon.
With that you can fish shakey heads, the mojo rig and the drop shot easily.
Get some finesse worms (Robos, Zoom, Strike King) and you are good to go!
I'm a big finesse fan! Good luck.
